A client reports experiencing leg pain while walking that improves with rest. The nurse should suspect which peripheral vascular disease?
A Deep vein thrombosis (DVT)
B Peripheral artery disease (PAD)
C Raynaud’s disease
D Varicose veins
The Correct answer and Explanation is:
The correct answer is B. Peripheral artery disease (PAD).
Explanation:
Peripheral artery disease (PAD) is a common circulatory condition where narrowed arteries reduce blood flow to the limbs, typically the legs. This restricted blood flow is usually caused by atherosclerosis, a buildup of fatty deposits (plaque) in the arteries. The hallmark symptom of PAD is intermittent claudication, which is the leg pain described by the client that occurs during activities like walking and subsides with rest. This happens because the muscles are not getting enough oxygen-rich blood during exertion, but the pain improves when the activity stops and blood flow returns to normal levels.
Key characteristics of PAD include:
- Pain in the legs during exertion (intermittent claudication): Clients often report a cramping, aching, or fatigue in the leg muscles during activities like walking or climbing stairs. The pain typically improves with rest because the oxygen demand in the muscles decreases.
- Weak or absent pulses in the lower extremities: Due to poor circulation, the pulses in the legs and feet may be diminished.
- Cool skin: The legs may feel cool to the touch as a result of reduced blood flow.
- Slow wound healing: Clients with PAD often have difficulty healing minor wounds or sores on their feet or legs because of inadequate blood supply, increasing the risk of infection.
In contrast:
- Deep vein thrombosis (DVT) (Option A) is characterized by the formation of a blood clot in a deep vein, usually in the legs. Symptoms include swelling, warmth, redness, and pain that does not improve with rest, unlike the intermittent claudication in PAD.
- Raynaud’s disease (Option C) is a condition that affects the arteries, typically in the hands and feet, causing them to narrow in response to cold or stress. Symptoms include color changes (white, blue, red) and numbness, but it is not typically associated with leg pain during walking.
- Varicose veins (Option D) are swollen, twisted veins visible just under the surface of the skin. While they can cause aching, heaviness, and cramping in the legs, they are not typically linked to the exercise-induced pain seen in PAD.
Thus, the client’s symptoms are consistent with PAD due to the nature of the pain experienced during walking and its relief with rest. Early detection and management of PAD are crucial to preventing complications such as non-healing ulcers or gangrene. Treatment may include lifestyle changes like smoking cessation, exercise, and medications to improve blood flow.
